Powdery solid cosmetic preparation

Abstract

An objective of the invention is to provide a powdered solid cosmetic that has excellent powder dispersibility and high impact resistance, while also having a texture similar to that in the case in which an elastic spherical powder is blended. The powdered solid cosmetic according to the present invention contains (A) a non-elastic spherical powder having a crushing strength per particle of 30 MPa or higher; (B) 1% to 15% by mass of iron oxide; (C) a gel-type partially crosslinked organopolysiloxane polymer; and (D) a non-ionic surfactant having an HLB of 10 or lower; wherein the (A) non-elastic spherical powder constitutes 90% by mass or more of all spherical powders contained in the cosmetic.

The invention claimed is: 
     
         1 . A powdered solid cosmetic containing:
 (A) a non-elastic spherical powder having a crushing strength per particle of 30 MPa or higher;   (B) 1% to 15% by mass of iron oxide;   (C) a gel-type partially crosslinked organopolysiloxane polymer; and   (D) a non-ionic surfactant having an HLB of 10 or lower;   wherein the (A) non-elastic spherical powder constitutes 90% by mass or more of all spherical powders contained in the cosmetic, wherein the cosmetic does not comprise an organic spherical powder.   
     
     
         2 . The powdered solid cosmetic according to  claim 1 , wherein the (A) non-elastic spherical powder is selected from among spherical silica, spherical alumina, spherical titania and spherical calcium carbonate. 
     
     
         3 . The powdered solid cosmetic according to  claim 1 , wherein the (C) gel-type partially crosslinked organopolysiloxane polymer is a dimethicone/vinyl dimethicone crosspolymer that has been swollen with a liquid silicone oil. 
     
     
         4 . The powdered solid cosmetic according to  claim 3 , wherein the liquid silicone oil is dimethicone. 
     
     
         5 . The powdered solid cosmetic according to  claim 1 , wherein the (D) non-ionic surfactant having an HLB of 10 or lower constitutes 0.01% to 5% by mass of the overall amount of the cosmetic.
